// I47 leg t /3 I F X United States Patent Ofiice 3,292,229 Patented Dec. 20, 1966 3,292 229 MACHINE FOR srmrrrNG CHENILLE CURLS FROM CORE THREADS Petr Georgievich Sergeev, Leningrad, U.S.S.R., assignor The invention relates to machines for producing imitation astrakhan fur, and particularly to machines for strippmg chenille curls from core threads. In order to produce imitation astrakhan, chenille tufts of equal length are secured to the core yarn to be subsequently curled in special machines. After being curled the chenille curls have to be separated from the core threads. Separation is effected in machines adapted for stripping chenille curl from the core threads.

Machines for producing imitation astrakhan fur are known. These machines are provided with a drawing mechanism, a device for stripping the chenille curls and a knife for cutting the core threads. The device for chenille curl stripping is made as a comb mounted on a swinging stand.

These machines are of complicated design and do not ensure full separation of chenille cur-ls from the cut core threads. As a result the imitation astrakha-n produced is of inferior quality and the use of these machines is limited by the aforementioned drawbacks.

Attempts to eliminate the aforementioned drawbacks have not proven successful.

Now it has been found possible to obviate said drawbacks if in the machine comprising drawing rollers mounted on the frame, and a flat knife located under the drawing rollers; a comb for chenille curls stripping and spiral knives for cutting the core threads in co-action with the flat knife are mounted on a reversibly rotating cylinder, mounted on the frame.

The object of the present invention is to simplify the machine. Another object of the present invention is to ensure full removal of chenille curls from core threads.

An important object of the invention is to increase production efliciency.

Having in view the aforementioned objects, the present invention is based on a new design of the machine and a new combination of parts and units.

It will be understood that the invention is not limited to the above described embodiment and various changes and modifications can be made without departing from the spirit of the invention.

For a better understanding there is given below a description of an embodiment of the invention with reference to the annexed drawings, wherein:

FIG. 1 is a front view of the machine partially cut away;

FIG. 2 is a side view of the machine as viewed in the direction of arrow A in FIG. 1;

FIG. 3 is atop view of the machine in FIG. 1; and

FIG. 4 diagrammatically illustrates the operation of the machine.

Upon the frame 1 are mounted drawing rollers 2 feeding the chenille 3 to the mechanism for cutting the core threads: This mechanism consists of flat knife 4 disposed under the drawing rollers and a spiral knife 5 mounted on a reversibly rotatable cylinder 6 and coacting with the knife 4. On the cylinder 6 is fixed a comb 7 for stripping the chenille curls. As it moves in one direction, the reversiby rotating cylinder 6 drives the comb 7 to grip the chenille curls and strip them from the core threads, and during the reverse travel the cylinder drives the spiral knife 5 to engage the flat knife 4, thus cutting the core threads after the curls have been stripped there from. The cylinder '6 is driven from an electric motor (not shown) installed on the frame 1 through a worm reducer 8 and a rod 9, connecting the worm reducer with a gear 10 secured on the axle of the reversibly rotating cylinder 6. The drawing rollers 2 are rotated by the wormreducer 8 through the rod 11, ratchet 12 (FIG. 3) and a. pair of gears 13, 14.

The chenille fed by the rollers 2 is unwound from the bobbins 15 mounted on the axles of the creel (not shown on the drawing).

The machine operates as follows: at the rotation of the drawing rollers 2 (FIG. 4), the chenille 3 coming from the bobbins 15 is fed into the zone of chenille curls strip ping and core threads cutting. At the same time the cylinder 6 turns counterclockwise and the comb 7 effects the removal of the chenille curls. Thereupon the cylinder turns in reverse direction and the spiral knife 5 coacts with the flat knife 4 and cuts off the core threads after which the operation is repeated.

What I claim is:

1. A machine for strip-ping chenille cur-ls from core threads of a chenille material, said machine comprising: a frame; a drawing mechanism mounted upon said frame for the feeding of chenille material; means for driving said drawing mechanism; a reversibly rotating cylinder mounted on the said frame under said drawing mechanism; means for stripping the chenille curls, mounted on the aforementioned cylinder; and means for cutting the core threads also mounted on said cylinder.

2. A machine for stripping chenille curls from its core threads of a chenille material, said machine comprising: a frame; drawing rollers mounted on said frame and ensuring feed of the chenille material into a zone for cutting the threads; means for driving said drawing rollers; a reversibly rotating cylinder mounted on said frame under the drawing rollers; a comb mounted on said cylinder for stripping of chenille curls from said core threads; and means for cutting the core threads also mounted on said cylinder.

3. A machine for stripping chenille curls from core threads of a chenille material, said machine comprising: drawing rollers mounted on said frame and ensuring feed of chenille material into a zone for cutting the core threads; means for rotating the said drawing rollers; a reversibly rotating cylinder mounted upon the frame under said drawing rollers; a comb mounted on said cylinder for stripping of chenille cur-ls from said core threads; a knife mounted on the frame above said cylinder; and spiral knives mounted on said cylinder and coacting with said knife to cut the core threads.

4. A machine for stripping chenille curls from core threads of a chenille material, said machine comprising: a frame, means mounted on said frame for the feed of chenille material, a cylinder rotatably mounted on said frame beneath the feed means and adapted for undergoing rotation in alternate opposite direction, a fixed knife adjacent the cylinder, the chenille material being fed between the fixed knife and the cylinder, a comb mounted on said cylinder for contacting the chenille material to strip the curls from the core threads as the cylinder ro- 3 4 tates in one direction of rotation, and a knife "also mount- 1,854,040 4/ 1932 Junkers 28-62 1 ed on the cylinder for cooperating with the fixed knife to 1,934,398 11/ 1933 Benowitz 28-62 I cut the core threads as the cylinder rotates in the opposite 2,203,561 6/1940 Broder 28-62 1 direction of rotation. 2,276,124 3/ 1942 Unger 28-62 5.
